Benefits of technology

The invention aims to solve problems with upgrading and modifying components in systems that require reverse compatibility. It also aims to reduce errors and injuries caused by inaccurate sample analysis and calibration. The invention provides means for increasing the number of calibration information that can be placed on a calibration label of a predetermined size and supplying auto-calibration data to multiple instruments. It also provides improved printing methods for isolating conductive data and increasing the amount of data provided in a predefined area. The invention also includes processes for improving glucose monitoring, cholesterol monitoring, and analyte level determination.

Problems solved by technology

If calibration codes adapted for characteristics of the new improved meters are used in older meters, test results are likely to be inaccurate.

Embodiment Construction

[0034]The prior art discloses a method and apparatus for calibrating a sensor instrument. The sensor is used in a sensor system that includes a sensor meter, a sensor for receiving a user sample to be analyzed and a processor for performing a predefined test sequence for measuring a predefined parameter value. A memory is coupled to the processor for storing predefined parameter data values. An auto-calibration code is associated with the sensor and read by the processor before the user sample to be measured is received. The auto-calibration code is used in measuring the predefined parameter data value to compensate for different characteristics of sensors which will vary on a batch to batch basis. Variations of this process will be apparent to those of ordinary skill in the art from the teachings disclosed herein, including but not limited to, the drawings and the claims.

[0035]Referring now to FIGS. 1-3, a prior art sensor meter 10 is illustrated. In FIG. 2, the inside of the senso...

Abstract

An auto-calibration label for use with one or more sensing instruments. The label includes first and second encoded calibration information. The second encoded calibration information may correspond to a different instrument than the first encoded calibration information. The second encoded information may also be used to provide additional calibration information for use with the first instrument. The label may be removably attached to a sensor package including a plurality of sensors. A first conductive ink pattern is disposed on the label to define the first encoded calibration information. The first conductive ink pattern is disposed contemporaneously with or without a portion of a second conductive ink pattern defining the second encoded calibration information. An insulating layer is disposed on the first pattern. The second ink pattern is disposed on the insulating layer. The first pattern is operable with the first instrument, not the second instrument. The second pattern is operable with the second instrument, not the first instrument.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims benefit to U.S. Provisional Application No. 60 / 409,331, filed on Sep. 10, 2002.FIELD OF THE INVENTION[0002]The present invention generally relates to sensor instruments, and, more particularly, to a new and improved method and apparatus for calibrating a sensor instrument. Particular embodiments relate to sensor packages for use with an analyte monitoring instrument.BACKGROUND OF THE INVENTION[0003]The field of clinical chemistry is concerned with the detection and quantitation of various substances in body material, typically body fluids such as blood, urine or saliva. In one important aspect of this field, the concentration of naturally occurring substances, such as cholesterol or glucose, in an individual's blood is determined. One of the most frequently used analytical devices in clinical chemistry for determining the concentration of an analyte in a fluid sample is the test sensor. Upon contacting the test sens...
